Greenland ice sheet is the second largest ice mass on Earth. As climate changes, the ice sheet surface melt is increasing and more and more fresh-water flows to the ocean, contributing to the global sea-level rise.
Glacier velocity is a vital part of monitoring and understanding the glacier system dynamics as well as its contribution to the global sea level. Satellite data is a suitable tool to monitor glacier velocity over large areas. Two methods are commonly used to derive speed of the ice flow from the satellite data: SAR interferometry and feature/speckle tracking (respectively with optical and SAR data) between consecutive acquisitions.
In this webinar, we will consider the second method applied to Sentinel-1 data to derive the glacier velocity of the Peterman Glacier (Greenland) using a RUS working environment. We will guide you to access the RUS Service and to download, process, analyse and visualize the free data acquired by the Copernicus satellites.
